ansible instructions fails with "No hosts matched"

[rafabene]

To workaround the problem I commented out and run become: yes and become_method: sudo from setup.yml.

After that I ran ansible-playbook -i setup-host setup.yml -sk instead of ansible-playbook -i setup-host setup.yml -k

Thanks for spotting this, wonder whether it works here. What Ansible version do you use ?

To be honest, I didn't thoroughly test the bootstrap process which is a bit rough.

The version I use on OS X is:

nsible --version
ansible 2.0.0.2
  config file =
  configured module search path = Default w/o overrides

[rafabene]

Ah! That explains much. I ran ansible from inside the pi. The version is: ansible 1.7.2. Shouldn't we add to the instructions that ansible2+ should be used and run from outside the pi ?

Ouch, sorry that should be in the README for sure.

The general idea is to use Ansible only for provisioning the Pis and then is not needed anymore, so there is not much benefit to have Ansible on the Pis (the communication ansible -> pi goes all via SSH).

Thanks for spotting this ;)

BTW, wrt the roadmap:

• I'm currently preparing a talk "Kubernetes for Java Developers" for next week at JAX2016 using the cluster as demo platform. For this I will tune the Kubernetes part (i.e. enable SkyDNS and add a registry).
• A Blog post and enhanced documentation about the initial setup.
• Afterwards I'll tackle OpenShift with an extra playbook. The idea is that you can easily switch between OpenShift and Kubernetes by running the appropriate playbook.

Any feedback is highly appreciated, let me know when I can help. I'm on irc, too (as @ro14nd on #fabric8 in Freenode)

Concerning the become: yes etc., it would be good if this would be in a separate config file. Currently I have to change it in 4 different files as in my setup I can (only) connect directly as root.

I will try to move the authentication configuration externally, good idea.
